The angle of deperession of aPt A, as measured form the top of abuilding 30m tall is 450, how far is A from the basc of the
building?
A. 97m B. 30m C. 45m D. 32m

B

Step-by-step explanation:

Given

Height of building

Angle of depression

Suppose distance of Point A from base of building be  

From diagram we can write

So, point A is from base of building

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
